Yikes, the entitlement is strong. Not now, nor ever have we been given 100% of the information in an open case. Yes, people are scared and curious by nature and want to know what the hell happened. They have to keep certain things to themselves. Also, I'm confused why I keep seeing this case being referenced as going cold? It's been 5 or 6 weeks? I believe everyone is working as diligently as they can, and this WILL be solved.
I also stand by my previous statements that the killer waited inside the house for them. I stated before that people from the town comment about how "safe" it is there, and people leave their doors unlocked and all kinds of stuff. I think we don't see any forced entry because the home wasn't locked to begin with and having a constant flow of people in and out, nobody would think twice if they saw someone enter the home late at night. Whether he specifically targeted one of the girls or had simply been watching the home previously and knew they would be "easy" targets. It would have been easy for him to familiarize himself with the layout had he never been there before, while he waited for them to get home. The house finally gets quiet, and he strikes. IMO
